2 Claims. (Cl. 299-154) This invention relates to a window drier for locomotives or any motor vehicle which is equipped with compressed air, and has for the primary object the provision of a device of this character which will direct compressed air over a comparatively wide area of the glass of a window or Windshield for driving or removing rain therefrom or for drying the glass of moisture which may accumulate thereon, so that a person may have clear vision through the glass without a moving element or part passing the line of vision of the person as occurs with the conventional type of glass wiper or cleaner.

With these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a fragmentary front elevation illustrating a device for drying a window of a locomotive or other vehicle and constructed in accordance with my invention.

Figure 2 is a sectional view taken on the line 2-2 of Figure 1.

Figure 3 is a sectional view taken on the line 3-3 of Figure 1.

Figure 4 is a sectional view taken on the line 4 4 of Figure 1.

To permit the cleaning or drying of a Window of a locomotive or any other type of vehicle by compressed air the present invention is suitably mounted on the Window frame 5 and consists primarily of an improved type of nozzle 6 including a body 1, and a connecting neck 8 internally threaded to permit a conduit or pipe 9 to be threaded therein. The conduit or pipe 9 is employed for conveying compressed air from a source on the locomotive or other vehicle to the nozzle and the latter acts to direct the compressed air over a wide area of the glass and also for a considerable distance as to the length of the glass so as to drive rain from the glass as Well as to dry the glass of any accumulated moisture permitting clear vision to be had through the glass without a moving part traversing the line of vision of the person.

The body 'I of the nozzle includes a front wall I0 narrowing in Width toward the neck 8. The body 'I further includes a rear straight wall II matching the width or size of the front wall and is adapted to rest atly against the glass I2 carried by the Window frame. The body I further includes side walls I3. The side Walls I3 are of substantially triangular shape, as indicated in Figure 2, the purpose of which is to permit the front Wall to slope toward the free edge of the rear wall. The free edge of the front Wall and the free edge of the rear wall are spaced to form an elongated discharge slot I4 inclining in the direction of the glass I2.

In order that the slot I4 may incline toward the glass as specied the free edges of the rear and front Walls are beveled. The front, rear and side walls are of integral construction as well as being integrally formed with the neck 8.

Formed on the inner face of the front wall is a plurality of substantially triangular shaped deectors I5 having the longest edges thereof integral with the front Wall With one short edge disposed opposite the rear wall and the other short edge disposed opposite the neck 8. The deectors I5 are arranged in pairs, as clearly shown in Figures 3 and 4. The deflectors of one pair are set on an angle to the other pair of deflectors and also as shown in Figure 1, the defiectors converge toward the neck 8.

The purpose of the deflectors I5 is to spread the flow of compressed air within the body I so that compressed air leaving the body by Way of the discharge slot I4 will be spread over a wide area or surface of the glass I2.

It will be seen that a practical type of nozzle has been devised for efficiently distributing compressed air from a source against and over a comparatively wide area of a glass so as to thoroughly remove rain, moisture or the like and to rapidly dry the glass.

It is to be understood that when the present invention is installed on a locomotive or a vehicle having compressed air the conduit 9 is connected to the source and will be equipped with a control or cut-0E valve.

While I have shown and described the preierred embodiment of my invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made Without departing from the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim is:

1. In a nozzle of the character described, an integral body and neck, said body embodying integral front, rear and side walls; said side walls converging towards said neck, and said rear wall being relatively at and straight and matching in Width said front wall; said side walls being flectors integral at one edge thereof with said 10 front Wall.

2. As a new article of manufacture, a nozzle of the class described embodying an integral body and neck, said body embodying front and rear Walls of substantially the same area, with the 15 front wall inclined at an angle to the axis of the neck and sloping from said neck in the general direction of said rear wall; said front and rear Walls having the free edges thereof beveled with the beveled surfaces of said edges confronting and coacting to dene therebetween a discharge slot inclining in the general direction of the rear wall, and said beveled edges being in closely spaced relation, and substantially triangularshaped deflectors integral, at the longest edges thereof, with said front wall, with one short edge of each deflector disposed opposite said rear wall and the other short edge thereof disposed opposite to and inwardly of the body from said neck.
